In each case, read the comments too.
I've decided to list these by field and topic and author, respectively (this allows multiple authors to cover one topic, as in Gene).
We don't want this to be a competitor to Wikipedia, but a chatty and useful resource for folk to get into whatever they need to at the start of learning a topic. If you know of older posts of this kind, do let me know by email. My address is john-dot-s-dot-wilkins-at-gmail-dot-com (make the obvious amendments by removing dashes and dots and replacing them with "." or "@"), or leave a comment.

Hi John,
I found this post through Bora's post on the biological clock.
These 2 posts may be good for the collection, if you want to include links more targeted to lay readers than to scientists.

A wiki may be the way to go. That will let people add their own posts and save you some work.
I converted your HTML to wiki (using this tool), then uploaded it to two different wikispaces
http://basicconcepts.wikispaces.com/
http://basicconcepts.pbwiki.com/
I'm not sure if they're exactly what you're looking for - they both lack some styling options and have text ads. In any case, I figured I'd upload it to both and let you guys decide. If anyone has a better recommendation for wiki hosting, it's easy to copy and paste the content over someplace new.

Posted by: Alon Levy | February 3, 2007 11:14 PM
John,
Since your list of links keeps growing and growing (and growing... and growing...), maybe it deserves a site of its own. I kind of cringe suggesting this (since deleting link spam could turn into a full time job for somebody), but maybe a wiki-style site for science tutorials wouldn't be such a bad thing all-in-all... Rather than have to host tutorials all over the place, people could just volunteer to maintain their own sections of the wiki.

Posted by: Sam Wise | February 5, 2007 10:20 PM
Sam, I am aware of a move at our Masters and Overlords to set this up as a separate blog. When the legal issues (copyright permissions) and formatting have been sorted, I'll announce it here. I'll continue to be involved.
Posted by: John Wilkins | February 7, 2007 11:54 PM
I've been meaning to stop by and thank you and the rest of the SciBlings for putting this together. I think it's going to be an invaluable resource -- I've already wiled away several hours perusing some of the posts -- and once there's a permanent home, I'll be placing a permanent link on my own blog.
Kudos to all, but especially John for overseeing the nuts and bolts...
Posted by: Jennifer Ouellette | February 12, 2007 06:06 PM
Hmm, if you fancy a fun read, go through Bad Science and pick something out. For example, on The Prosecutor's Fallacy.
Hmmm, a bit of cross-fertilisation might be required. Back soon.

I'd be interested in learning how scientists are able to trace a particular protein back to its gene. In other words, once a biochemist notices that something cool is going on in a cell, how does she discover which protein is doing this interesting task. And once she's isolated the protein, how does she find it in the genome? I assume that there is a clear and simple was to explain this, but I'm not sure who's blog to direct it to.
Posted by: Matt | February 19, 2007 11:57 PM
Matt, I passed your question on to some folks. If anything comes of it, I'll announce it here.
Posted by: John Wilkins | February 20, 2007 12:03 AM
Matt, I have been referred to this post at Science Creative Quarterly, as a partial answer to your question.

http://scientianatura.blogspot.com/2006/10/fraud-of-homeopathy.html
Posted by: joshua chong | February 21, 2007 04:41 AM
A nice piece, but not an introduction of a basic science concept, I'm afraid. I'm being editorial and making an executive decision.
Posted by: John Wilkins | February 21, 2007 05:01 AM
Thanks for the referral John, it certainly addresses part of my question. I guess my question is more broad...not just how is an unidentified protein characterized, but how is a specific action in the cell traced back to it's protein? You've already been very helpful, hopefully some other ScienceBlogger will step up to the plate ;-)
Posted by: Matt | February 21, 2007 11:31 PM
Here's a more in-depth consideration of the definition of a gene:

Posted by: Allen MacNeill | February 27, 2007 08:48 AM
Could I suggest making a little adjustment to your taxonomy? I think you're accumulating enough posts under the heading "Mathematics, Philosophy, Logic and Computer Science" to justify splitting math, philosophy and comp sci into separate headings (and logic posts could go into any of those three depending on the particular slant of the post).
Some of Mark's posts that are currently listed under General Math are probably better categorized as comp sci: Recursion, Turing Machine, The Halting Problem, and Algorithm, while his Sets post is more like General Math.
Not that I would want try to micromanage your great work here. I can feel my hair getting pointy already.
Posted by: Kurt | February 28, 2007 09:34 AM
Yes, it is getting unmanageable, isn't it? I don't quite know how to set it all out. And it's only going to get worse. I think I may split the post into one for each science, and just link to them from the Basic Concepts main post.
Go all pointy haired. I can take it. I have worked for worse managers in my time...
Posted by: John Wilkins | February 28, 2007 09:37 AM
I don't know if this is too basic, but I just wrote a post on the difference between percentage and percentage points.

Where is a guide to Plate Tectonics? and lots of other earth science concepts?
Posted by: Bonnie | March 5, 2007 03:15 PM
One minor correction - it's Wager as in the English word, not Wagner was the German surname. Common mistake.
Posted by: Kristjan Wager | March 6, 2007 12:48 AM
Duly corrected. I was being so careful to spell your first name right...
Posted by: John Wilkins | March 6, 2007 02:26 AM
And don't think I don't appreciate that. Once I renewed my passport, they had spelled my first name wrong *sigh*
Posted by: Kristjan Wager | March 6, 2007 05:56 AM
How big do you think this list will eventually? And in some sense is this project asymptotically converging on the same end result as (a subset of) wikipedia?
I guess these little blurbs are single-authored and presumed to be authored by professionals or expert amateurs in the subject, which is different. But the user experience is pretty close.
Maybe this collection is sufficiently different to be separate from wikipedia, but it could still stand to have its own wiki-like organization, so that, for instance, a not-so-basic concept like anisogamy could point to the more-basic concepts like "sexual reproduction" and "evolutionary stable strategy".
Posted by: mtraven | March 8, 2007 05:31 PM
It is reaching critical mass, and we are going to have to do something about organisation soon. I think it will need to be a separate site, with main entries for each subject topic, linking to the relevant posts, all linked from a "sticky" post at the top.
It will take some time to set up properly, so I'll have to ruminate upon it. Any suggestions are welcomed here, particularly if they are on how to arrange the material.

Via "Primitive" (under Evolution and Phylogenetics) I just get to "Page Not Found"
Posted by: Enigman | March 10, 2007 05:17 AM
Fixed now.
Posted by: John Wilkins | March 10, 2007 06:16 AM
Just a small note about my entry - I thought it was too basic to be relevant, but I have noticed that I get a few visits per day through google searches, so it must have hit a needed niche.
In other words, I would warn against staying away from a topic, just because it might appear too basic - it might be relevant to someone out there.
Posted by: Kristjan Wager | March 11, 2007 04:26 PM
You know you've been reading Scienceblogs too much when...
on seeing "Basics: Guidelines for Using a Cellphone Abroad" as most e-mailed in the New York Times site, you think "John Wilkins is stretching it a bit, isn't he?"
Posted by: jim | March 20, 2007 04:54 AM
John,
Thanks for the mention (Metric System under General Math). For the record though, I wrote it (not Doc Bushwell). The confusion is understandable as ours is a three-way blog.
Posted by: Jim | March 22, 2007 12:35 PM
Some ideas for subjects
1. Occam's Razor.
2. Symmetry and Laws of conservation.
3. Computability
4. Godel's theorem
